Building insulation materials to improve quality, meet the needs of green building

[] the total amount of GDP in China is expected to increase by 7% in 2015. (the third quarter of this year, GDP grew by 6.9%) the current economic downward pressure, the slowdown in fixed asset investment, real estate, new construction area and sales area declined, and the increasing pressure on the stock, mainly cement, steel and other building materials market, building materials industry in the downturn, so many companies think insulation materials industry will be hit. Woeful. We believe that the current thermal insulation materials industry into the transformation and upgrading, mergers and acquisitions is inevitable, but the whole industry, the outlook is still promising. Why?1, energy conservation is the eternal theme of economic developmentOur country needs resources, especially energy. Is expected to 2050, China’s energy demand is about three times now, since 2005, the national investment in the energy sector more than other industries, in ten years, invested approximately $400 billion for the 1 billion 400 million energy supply security.Open source, on the one hand, must also conserve energy. Building energy consumption accounts for 23% of the total energy consumption of the society. In the future, China’s rural concentrated residential village, and efforts to increase the area of hot summer and cold winter began the development of central heating, large public buildings for the construction of an increasingly large proportion of … … these new trends will have a significant impact on building energy consumption, to further save energy.2, China’s real estate industry still has room for developmentMacroscopically speaking, compared with developed countries, China’s economy is still in the stage of development and has great potential for growth. National new urbanization plan issued by the State Council “(2014-2020)” shows that China’s industrialization and urbanization is in a period of rapid development, 3 “ 100 million ” (about 100 million to promote the transfer of agricultural population settled in the town, reconstruction of about 100 million people live in shanty towns and villages in the city, guide approximately 100 million people in the Midwest the nearest town area. ) there will be a larger housing demand. Demand for primary housing and improved housing remains strong, and the desire of residents to improve their home environment remains strong.From the real estate industry, is still in the overall decline in the situation, but since the beginning of this year, the government introduced a number of policies to promote housing consumption, the real estate enterprise funds in March 2015 began to pick up momentum. From the data released by the National Bureau of statistics in October 19th, China’s first three quarters of GDP grew by 6.9%. National real estate development investment 7 trillion yuan, an actual growth of 4.2%, of which residential investment growth of 1.7%. Housing new construction area of 1 billion 148 million square meters, down 12.6%. Among them, the new residential construction area decreased by 13.5%. National commercial housing sales area of 830 million square meters, an increase of 7.5%, of which residential sales area increased by 8.2%, the real estate situation as a whole warmer signs. The development of the real estate industry to stabilize, but don’t expect a few years back as hot. Even if the new construction area has dropped, the state should maintain a relatively smooth operation of the real estate industry, but also still need to build energy-efficient construction standards, which also need to use insulation materials.3, new building energy efficiency design standards improvedPeople’s demands for quality of life are constantly improving, and higher demands are made for the quality of service in construction. At present, the mandatory standard of building energy efficiency is low, even if the &ldquo is being implemented in large and medium-sized cities all over the country; the three step is to save energy ” the standard is only equivalent to the level of Germany in the early 90s, and the energy consumption is 2 times that of germany. In order to speed up the pace of energy saving and emission reduction, it is necessary to carry out the new energy saving design standards as soon as possible. Beijing and Tianjin have introduced energy-saving design standards for residential buildings with energy efficiency of 75% and public building energy efficiency rate of 65%. The design standard for energy efficiency of residential buildings in Tianjin city as an example to estimate the heat transfer coefficient of wall 9 layer above the limit value from 0.70W\/ (m.K) to 0.45W\/ (m.K), a decline of 36%, such as the use of molded polystyrene board as the heat preservation layer whose thickness increases from 70mm to 100mm, building insulation materials market demand will rapidly expand.4, the existing building energy saving task is arduousAt present, China has a construction area of about 46 billion square meters, of which the northern town has a construction area of about 8 billion square meters, there are a large number of existing buildings, the need for energy-saving transformation. “The existing residential building energy-saving” technical specification for JGJ\/T129-2012 was implemented in March 2013, requirements of heat transfer coefficient of building envelope in cold areas shall comply with relevant provisions of the current industry standard “living in severe cold and cold regions in building energy saving design standard” JGJ26, will still need a large number of insulation materials.On the other hand, for the construction of energy-efficient residential since 90s, has been used for more than 20 years, a considerable number of residential will enter the maintenance period. A major inspection of the quality and durability of the exterior wall insulation will be carried out. At that time, a new round of existing buildings for energy conservation needs a lot of thermal insulation materials.5, accelerate the pace of building a new socialist countrysideChina’s annual agricultural area increased by about 800 million square meters. According to the total amount, accounting for 34% of the total energy consumption of the building (2008), the indoor temperature in the northern rural areas was lower than that of the urban residential buildings in the same climate zone, and the indoor temperature was 7-9 degrees lower, and the general heat comfort was poor. The national standard “2013 rural residential building energy efficiency design standard” GB\/T50824-2013 implementation, &ldquo 13th Five-Year; ” rural building energy transformation period will start will also need a large number of insulation materials. With the development of economy, people’s quality of life and higher building comfort requirements are also due to the construction of its own characteristics, belongs to the long-term energy industry, with a substantial increase in the stock of building the total building energy consumption increasing. Therefore, it is necessary to solve the contradiction between the quality of construction services and the growth trend of building energy consumption.6, green buildings and green building materials are developing rapidlyIn 2013, the general office of the State Council issued document No. 1 (2013) transmitted the national development and Reform Commission and the Ministry of housing and urban development of the “green building action plan” requirements of &ldquo ” comprehensively promote the development of green building;. The seventh is to develop green building materials, green building materials to study the establishment of certification system, preparation of green building materials products directory, guide and standardize the market consumption, also proposed to promote the construction of industrialization, promote the construction waste resource utilization requirements. In May 2014, the Ministry of housing and the Ministry of industry jointly issued the “green building materials evaluation mark management measures”, the preparation of the national green building materials evaluation standards and rules have also entered the consultation stage.At the end of 2014, China revised and promulgated the green building evaluation standard GB\/T50378-2014. Local standards have also been introduced in Beijing and Tianjin. At the same time, Beijing, Tianjin and Shanghai plans to require all civil architectural design to meet the green building star standard. Tianjin has also compiled the guidelines for the technical evaluation of green building materials (Trial Implementation), which puts forward higher requirements for the greening of thermal insulation materials. Its main performance, such as combustion performance, dimensional stability, thermal conductivity and so on, according to their advantages and disadvantages of the provisions of the scoring.In August 2015 31 the Ministry and the Ministry of housing jointly issued “to promote green building materials production and application of action plan” proposed in 2018 in the green building materials industry main business income in the proportion increased to 20%, the proportion of new buildings in the application of green building materials green building applications reached 30%, the proportion reached 50%, the pilot project application ratio reached 70% the transformation of the existing building applications increased to 80%. The development of insulating material cannot be separated from the green, only the flow, there is hope.In summary, we believe that the prospects for building insulation materials are still promising, but to improve the quality, to meet the needs of building energy conservation, especially green buildings.So, the real development of green insulation materials is to make great efforts, BIM digital technology and Internet, with the development of large data, 3D printing, industrial revolution 4 and thermal insulation material has a close relationship, must take the innovation in mind, realizing the green dream as soon as possible.Review the past few years, insulation materials industry showed great toughness, not only did not collapse, and have greater development.
